Have you tried to force the spindle to run by linking the run command input on the spindle drive ? This will eliminate any interlocking (eg guard switch) issues - that is, if the Orac had any ?

I believe this is your spindle drive :

I'd definately go down the route of getting the drive to run by linking the run / enable with your own switch (4,5,6) and a pot on the speed control pins (1,2,3)
If that works, then you'll be looking for old, broken or corroded wiring is my guess.

I presume you've found and checked all the fuses ?
